"After years of encouragement from the OpenBSD community for others to use Reyk Floeter's free atheros wireless driver, it seems that the Linux world is finally listening. Unfortunately, they seem to think that they can strip the BSD license right out of it." Update: The issue has been fixed, but sadly, lkml.org is down, so I cannot give any links just yet.

BSD is not about real freedom. BSD is about not protecting the granted rights.
GPL is not about real freedom. GPL is about protecting granted rights. That's part of what makes it "viral".

The BSD license *does* protect the rights it grants. The code released under the BSD license (whichever version you pick) will always remain free for *anybody* to use for whatever purpose, provided the copyright notice is not unlawfully stripped out.

The GPL license is not only about protecting granted rights, but also about telling people what they can or can't do with *their own* source code.

All this descends from the very different concepts of "freedom" that lie at the basis of the two licenses.
It's pretty evident that the "freedom" defined by the FSF is much closer to the meaning of that word in a socialist country than it is to the meaning of that word in a capitalist country, where "freedom" isn't generally obtained by telling people what they may or may not do with their own stuff.
